SPECIFICATION forming part of Letters Patent No. 668,419, dated February19, 1901.

Application filed August 21, 1900. Serial No. 27,602. (No model.)

To to whom it may concern:

Be it known that I, OSCAR RUSSELL, a citizen of the United States,residing at Sycamore, in the county of Dekalb and State of Illinois,have invented new and useful Im provements in Machines for InsulatingOverhead Wires, of which the following is a specification.

My invention relates to machines for coating overhead electric wireswith a liquid insulating material; and the object of my invention is toprovide simple and efficient means for thoroughly coating the wireseither before or after they have been attached to the poles. I attainthis object and advantage by means of the construction shown in theaccompanying drawings, which form a part of the speci-" fication, and inwhich Figure 1 is a central longitudinal section of a machineconstructed in accordance with my invention, the hinged cover beingopen. Fig. 2 isasimilar view, the cover being closed. Fig. 3 is a planview of my invention, the cover being thrown back. Fig. 4 is atransverse section showing the spring-bearings of the pulley. Fig. 5 isa plan view of the outside of the cover.

Like numerals of reference designate like parts wherever they occur inthe different views of the drawings.

In said drawings the numeral 1 designates a box or casing havinginclined lower sides or bottom 2 and provided with a reservoir 3 forcontaining a liquid insulating material, the bottom of said reservoirbeing inclined in order that the liquid may flow toward the centerthereof. A pulley or sheave 4 is j ournaled in the reservoir on atransverse shaft 5, having spring-bearings 6, which permit the pulley torise and fall as inequalities in the wire ride over it. tition 7 in thereservoir 3 consists of two inclined sections 8 9, apertured to admitthe pulley or wheel 4 and resting on ledges or supports 10, secured tothe sides of the casing 1. An arm 11, pivoted in bearings 12 on thesection 9 of the reservoir-partition 7, carries at its opposite end arubber block 13, having a semicircular groove 14 in its face. This blockis attached by screws or bolts to the seat 16, secured at one end of ashank 17, which extends down through an opening 18 Ahorizontally-extending parin the section 9 and aspring 19, surroundingthe shank, and forms a cushion-seat for the rubber block to allow forkinks and inequalities in the wires being treated. A similar arm 11 ispivoted in bearings 12 on the hinged cover for the box or casing, andsaid arm has a similar block of rubber 13, seated on a shank 17,extending through the cover 20 and having a spring 19 surrounding saidshank. These two arms 11 11 with the grooved blocks and the springs,form a pair of yielding jaws which form guides for the Wire. The springs19 19 permit the jaws to separate a sufficient distance to compensatefor kinks or inequalities in the wire.

A pair of wipers consisting of grooved rubber blocks 22 22 are suitablyconnected to flanged seats 23 23, secured to the ends 24 24 of levers 2525. These levers are fulcrumed intermediate their ends at 26 26 to theinside surface of the cover 20, and their ends opposite the wiper-jawsare connected to the arms of a U-shaped spring 27, secured by keepers 28to the cover 20. The tendency of the spring is to close the wiper-jaws,and the levers 25 25 may be separated to open the jaws by means of a key29, pivoted in the cover 20 and having two arms 30 30, which bear atopposite points upon the levers 25 25 when said key is turned by thecrank or handle 31 on the outside of the cover.-

A piece of rubber 32 is held bya clamp 33, attached to the inside of thecover 20, said piece of rubber having a groove 34 to bear upon the wireimmediately over the wheel or pulley 4, and the purpose of said rubberpiece being to wipe back the superfluous insulating liquid as the wirepasses over the pulley or wheel.

A ring or handle 35, connected to the shank 17 on the outside of thecover, serves to separate the jaws 13 13 when desired.

A roller 36 is journaled in bearings 37, secured inside the cover 20,which roller serves as a guide and support for the wire as it passesfrom the jaws 13 13 to the wipers 21 21.

A roller 38 is journaled in a hanger 39, having a slotted arm 40adjustably mounted on the cover 20 at the inlet end of the casing. Thearm 40 is seated upon an inclined support 41, secured to the cover.

Openings 42 43 are formed in the casing or box to permit the wire topass through it, and an eye or loop 44 is attached to one end of theinclined bottom 2 to serve as an attach ment for a Wire or rope forpulling the device over the wire.

The operation of myinvention is as follows: The-cover 20 is raised andthe wire to be insulated is passed through the openings 42 43 over thewheel or pulley 4, and when the door is closed the wire passes betweenthe jaws 11 11 and the wipers 21 21". When the casing is drawn forward,the wheel 4 carries the insulating material up and applies it to thewire, and the rubber blocks and wipers distribute ituniforml y upon thewire at all points.

Having thus fully described myinvention, what I claim is 1. A machinefor insulating overhead wires, consisting of a box or casing, containinga reservoir for insulating liquid, a wheel journaled to dip into theliquid, and spring pressed wiper-jaws mounted in the casing,substantially as described.

2. In a machine for insulating overhead wires, the combination with abox having a partition therein thus forming a well or reservoir forcontaining insulating material and said box at each end formed with ahole or opening for the passage of a wire, of the hinged cover and thecentral wheel dipping into said well, substantially as described.

3. In a machine for insulating wires, the combination, with a boxconstructed to contain liquid insulating material, and having a coverthereon, of the wheel mounted to dip into the liquid, of the spring-armsmounted on the cover of said box and provided with blocks havinglongitudinal grooves therein, of a first spring-actuated arm mounted onthe cover and a second spring actuated arm mounted in the box anddesigned to act in combination with said first'spring-actuated arm,substantially as described.

4. In a machine for insulating wires, the combination, substantially asdescribed, with a box having a reservoir therein for liquid insulatingmaterial and a cover, of a wheel mounted to dip into said reservoir, anda pair of spring-actualed arms bearing wipers and mounted on said cover.

5. In a machine for coating wires, in combination with a box having areservoir therein and a cover, of a wheel mounted to dip into saidreservoir, a first spring-actuated arm mounted on the cover and bearinga grooved wiper, and a second spring actuated arm mounted in said boxand bearing a grooved wiper, said second arm being designed to act incombination with said first arm to embrace and wipe the wire.

6. In a machine for coating wire, the combination with a box having areservoir therein and an inclined horizontally-extending partition, thewheel dipping into said reservoir, spring-actuated wiper-jaws mounted toembrace the wire, and guides for said wire, substantially as described.

7. The combination, substantially as described, of a reservoirconstructed to contain liquid, spring-bearings, a sheave mounted on ashaft journaled in said spring-bearings, said sheave being located todip into the liquid in said reservoir.

8. The combination, substantially as described, of a U-shaped spring,two levers fulcrumed intermediate their ends and secured to the arms ofsaid spring, and grooved blocks mounted on the free arms of said leversand positioned to form jaws for embracing the wire.

9. In a machine of the class described, the combination, substantiallyas described, of a pair of pivoted arms, grooved blocks mounted on thefree ends of said arms, a shank mounted to slide and secured to saidarms, and spiral springs surrounding said shanks and mounted to actuatesaid arms.

In testimony whereof I have hereunto set -my hand in presence of twosubscribing witnesses.

OSCAR RUSSELL.
